Friction welding device for automobile wheel

Abstract

The invention relates to a friction stir welding device, in particular to a friction welding device for an automobile wheel. The invention aims to provide the friction welding device for the automobile wheel. The friction welding device for the automobile wheel comprises a working box table, an automatic part conveying device, a clamping and rotating device, a friction preheating device, a spoke,a rim, an electric rotary shaft and a telescopic stirring head. The automatic part conveying device is arranged on the right side of the top end of the working box table, the left side of the bottom in the working box table is welded to the clamping and rotating device, the left side of the top in the working box table is connected to the friction preheating device, and the rim is arranged on theleft side of the top of the working box table. The friction stir welding device achieves an effect of welding the automobile wheel full-automatically, safely and quickly by automatically conveying therim and internally clamping the rim stably first, then improving the rim temperature by friction, and finally carrying out welding to separate a stirring needle from the rim in advance.

Description

technical field [0001] The invention relates to a friction stir welding device, in particular to an automobile wheel friction welding device. Background technique [0002] Friction stir welding refers to the use of the heat generated by the friction between the high-speed rotating welding tool and the workpiece to locally plasticize the material to be welded. When the stirring shoulder of the welding tool moves forward along the welding interface, the plasticized material rotates in the stirring shoulder Under the action of friction, it flows from the front of the welding tool to the rear, and forms a dense solid-phase weld under the extrusion of the welding tool. As one of the important parts of the car, the manufacturing process of the wheel must be very rigorous. The existing wheel friction stir With the rapid development of science and technology, the welding device has also been improved technically. However, in the new friction stir welding device of the existing techn...

Problems solved by technology

[0003] In order to overcome the problem of the new friction stir welding device in the prior art, the present invention will continue to advance for a certain distance when the stirring pin leaves the weld to complete the welding work, causing the stirring shoulder to rub off excessive rims, seriously affecting the quality of the wheels, and requiring a large amount of consumption for later repairs time; in low temperature environment, the metal rim becomes brittle, and it is easy to crack under strong pressure, resulting in the scrapping of the whole material; in low temperature environment, it is difficult to clamp and fix the cylindrical rim from the outside, and unstable clamping is easy to cause accidents; in low temperature environment, workers manually place parts Contact with metal for a long time will easily cause frostbite to hands, and wearing gloves will affect workers’ operation. The technical problem to be solved by this invention is to provide a friction welding device for automobile wheels
